Controller 类

@Controller
@RequestMapping("/controller")
public class TestController {

    @Autowired
    private TestServiceImpl testService;

    @RequestMapping(value = "/test",method = RequestMethod.GET)
    public ModelAndView test(){
        testService.testServiceMethod();
        return new ModelAndView("index");
    }

}

存储库

public interface TestRepository extends CrudRepository<TestModel,Long>{

}

服务

@Service
@Transactional
public class TestServiceImpl {

    @Autowired
    private TestRepository testRepository;

    public void testServiceMethod(){
        TestModel model = new TestModel();
        testRepository.save(model);
    }

}

访问下面的 Controller 时出现错误。重要的是我可以获取entityManager并通常将对象保存到数据库中，因此错误位于Sping Data Jpa的配置中的某个位置。

刚刚发现这个问题，对缺乏答案感到失望，因为我也遇到了同样的问题。我想 OP 已经过去很久了，但其他人可能会发现这很有用。

我发现 Spring Data 和 Spring 的其余部分之间似乎存在兼容性问题 - 并非所有版本的 Spring Data 都适用于所有版本的 Spring，并且我没有找到任何提供兼容性信息的文档。

我使用的是 Spring 版本 4.0.0，在 Spring Data 版本 1.9.4 和 1.8.2 中都遇到了同样的问题，但在 1.7.4 中运行正常。

尝试调整您的版本(降级 Spring Data 或升级 Spring)，直到找到有效的组合。
